AUTOMATIC STOPPING AND LOCKING DEVICE FOR BRUSH-MACHINES.

Application lecl September 8, 1914.

To all lwhom t may concern.'

Be it known that I, TIEN RY ALBERT GLssoN, a citizen of the UnitedStates, and a resident of Cincinnati, in the county of Hamilton andState Vof Ohio7 have invented certain new and useful Improvements inAutomatic Stoppin and Lockingq Devices for Brush- Machines, of which thefollowing is a full, clear, and exact description.

This invention relates to automatic stopping, and locking devices forbrush machines.

The object of the invention is to provide automatic means on brushmachines for stopping the drilling and filling tools at a certainpredetermined time, and stopping the'movement of the work supportingmembers at a predetermined time, in order to keep all the actuatingmechanism in proper timed relation, and in position for the beginning ofanother cycle of operation.

In brush machines such as illustrated and described in my co-pendingapplication Serial Number 832,659 filed April 17, 1914, it is necessaryto provide automatic stopping means for stopping the drilling andfilling tools in proper timed relation one with the other and withrelation to the operating mechanism, in order to avoid the breaking ofeither of the tools by the movement of the work supporting members whilethe drilling and filling tools are engaging same. Furthermore, thedifferent actuating parts of the machine must not travel beyond theirproper position after the brush back has been completely bored andfilled, owing to the difficulty in bringing` the actuating parts of themachine back again to their proper starting position.

Another object of this invention is to pro vide an automatic stop forall the actuating mechanism of the brush machine making it possible tostop the different actuating parts of the machine at any desired pointin their cycle of operation,

In the machine to which this device is applied, a reciprocating androtating master drum is employed which is provided with a series ofactuating bars mounted thereon which operate the mechanism for movingthe work supportingl membersby engaging same and pushing said mechanismto one side or the other as desired. In a complete cycle of rotation ofsaid drum one brush back is bored and filled, and if there Specificationof Letters Patent.

are ninety holes in the brush back, ninety actuating bars have been usedin the operation, and in order to bring the first actuating bar back toits starting position the drum must continue to rotate after the brushback has been completed, provided there are, say 100 bars on the drum.But, however, the drilling and filling tools must stop in their startingposition immediately upon the finishing of the boring and filling of thebrush back.

Therefore, it is necessary to provide an automatic stopping device forthe machine which will stop the drilling and filling tools at the propertime, but will allow the drum to rotate further a certain distancebefore stopping, in order to complete its cycle of operation.

My invention consists in certain combinations of parts and details ofconstruction as will be described in the following specification andpointed out in the appended claims.

The brush machine to which this invention is applied employs operating`mechanism for the work supporting members and also means for the boringmechanism, said means however, preferably deriving their power from thesame source. The operation of the work supporting members is stopped byindependent means, coperating` with the driving means of the machineafter the boring mechanism has been stopped. This is necessary in orderto provide for brush backs of various sizes having more or less holes ortufts.

The 'ivorlr supporting members 6 and their operation-'are fullyexplained and illustrated :in my aforesaidco-pending application, and itis not deemed necessary to describe :them :in detail ahere.

L1-reciprocating and rotating master drum 7 is mounted on reciprocating:bearings or 'rollers 8 which opera-te von tracks 9.

Actuaitir-g vbars 10 Aare mounted in :slots faround the periphery ofthedrum 7 and con trol the movement of actuating mechanism (shown in ageneral Way at 11) alll of which ift :is not thought necessary toillustrate `in this application inasmuch as a full detailed descriptionthereof is found in my aforesaid copending application and it formssubeet matter for the said application.

. rx'llhe mechanism 11 operates the Work supporting :members in a numberof vdifferent directions relative to lthe drilling and filling tools 12.Tfhemaster drum 7 is mounted'on the sleeve 13. rlhe sleeve 13 is mountedon the dri-ve shaft 14 which is driven by the pulley 115 which in turnyis driven by a belt or any 4other sui-table means. The shaft 14 iliasa-pulley 17 mounted at the opposite endV from that of rthe pulley and abelt 1S connects same With the fly Wheel 19 thereby driving said flyWheel.

"The ffly wheel 19 is mounted on a sleeve 21 near the front of thevmachine and the sleeve in ytuJn is mounted on the sha-ft 2O (Fig. 2)said sleeve bei-ng mounted in a fbearing 22 saidbearing being properly'mounted on one of the legs 2 ofthe frame of the machine. The shafty 2Ois mounted in a suitable bearing 23 in one of the legs 2 of the frame ofthe machine -at the opposite end from that upon `which the fly Wheel ismounted.

Mounted tight upon the sh aft is a 'bevel gear 24C which vis providedwith clutch lteeth 25 for engagement with a clutch memberQG which is4provided with the recesses 27 ofthe clutch for interlockirg With Itheclutch teeth 25 ,of the vgear 2l.

Thus, the shaft 29 actuates the boring mech-l anism bymeans ofmechanism, (not shown) said mechanism formingno part of this inventionand 'being Well Aknown in the art, and therefore not considerednecessaryv to illustrate.

The KAbevel gear '36 meshes lwith bevel gear 54 which is rigidlyvmounted 'on a shaft 56 said shaftibein-g mounted yin Vsuitable bearingson the frame of "the machine, and bevel gear 58 mounted at the :otherend of said shaft 56 meshing with fa bevel gear 59 which is mounted onthe sleeve 13 'Which sleeve operates reciprocating and rotatingmechanism for the master drum t7. i

Mounted Aon'the shaft '5.6 l 'provide -a Worm Wheel 'G0 whichmeshesavith'the Worm Wheel 61 tightly mountedon 4the' stud or shaft 62.This Worm Wheel y6'1 carries ,the dials or disks 48 and 49 the formerbeing in `this ease adjustable circumferentially on the shaft 62 bymeans of the slot 64 and cap screw 65.

In order to stop the reciprocating movement of the boring mechanism Ipro-vide the connecting rod 66 (Fig. 3) which connects the leveroperating rocker arm 34 with the slidalole extension 67` on the slidingmember 68 having an extension 69 which engages the recess 7 0 in thedriving cam 71, which driving cam is mounted onA the shaft 20. The

sliding member 68 is mounted in the bearing 72 and has a pin 7 3extending laterally therefrom and passing through the slots 74 in thebearing 72. Thus when the rocker arm 134 is in the position shown inFig. 3 the extension 69 is locking the driving cam 71 against rotation.

In order to cause the fly wheel 19 to drive the mechanism of the machineI provide a clutch which will now be described. The fly-wheel isprovided with the hub 75 which rotates on a bushing or sleeve 76 Whichis keyed by means of the key 77 to the sleeve 21 on the shaft 20. Thissleeve 76 is provided with a paw] 78 (Figs. 2 and 5) which pavvl isrigidly mounted on the key 79, said key being semicircular in crosssection as shown in Fig. 8. The key 79 rests normally in a semicircularslot in the sleeve or bushing 76 and is mounted in the lugs 80 on saidsleeve76 as best shown in Figs. 2 and 5. The pawl 78 is provided with acompression spring 81 mounted at the end thereof, said compressionspring passing into a recess 82 in the sleeve or bushing 76 and tendingto force said pawl to its outermost position shown in dotted lines inFig. 5. A series of slots 83 are provided in the hub 75 of the flywheel, each slot being provided with a horizontal steel key or block 84for engagement with the key 79. Now when the pawl 78 is allowedto reachits dotted line position shown in Fig. 5 the half round key 79 willassume the position shown in Fig. 7 as soon as one of the slots 83 inthe hub 75 of the fly wheel has reached the proper position thus causingthe iy wheel to drive the bushing 76 and in turn drive all the othermechanism connected 'therewith.

The pawl 78 is normally held in the position shown in Fig. 5 by the pin85. This pin 85 is mounted in a bracket 86 (Fig. 3) the bracket beingsuitably mounted on the frame of the machine and being provided with theslot 87 through which the connection or pin 88 extends from the slidingpin 85. The pin 88 is in turn fastened to an arm 89 which in turn ismounted on a rocker arm 90 and is reciprocated thereby. This rocker arm90 is rigidly fastened to the shaft 39 as shown in Fig. 1, and isprovided with two extending lugs 91 projecting on each side of theoperating rocker arm 34 and allowing a considerable amount of play forthe rocker arm 34 to operate there-between. To adjust this amount ofplay I provide the set screw 93 which may be adjusted to increase ordecrease the amount of play as desired. The bracket 86 which carries thepin 85 also carries the pin 94 below the pin 85. This pin is alsoslidably mounted in the arm v86 and operated by the moving bracket 89 ina similar manner. It is the purpose of this pin to form a stop for thesleeve or bushing 76 which is provided with the flange 95 having the eX-tension 96 for engagement with said pin 94. Thus it is seen that the pin94 will prevent rotating so far as to allow the pawl 78 to travel pastthe stopping pin 85.

The operation of the stopping device is as follows:

The fly wheel being driven constantly, is

.engaged and disengaged by means of the semicircular key 79. When thehandle 44 is raised the operating rocker arm 34 is moved inwardly andimmediately causes the members of the clutch A to engage each other, theteeth always being in proper relation due to the stopping mechanism forthe cam 71 includingthe pin 69. The shaft 20 begins to rotateimmediately upon the engagement of the clutch A, and clutch A alsooperates the bevel gear 36 which in turn operates the bevel gear 54,thereby operating the shaft 56. The shaft 56, it is readily seen,operates the master drum by means of the bevel gear 58. The worm 60being mounted on the shaft 56 operates the worm wheel 61 and is properlygaged so as to move the worm wheel 61 one tooth circumferentially whileit is making one revolution. Thus the worm wheel 61 is provided wit-h asmany teeth as there are slots for the bars 10 in the master drum. Thedisks 0r dials 48 and 49 are mounted on the worm wheel. 61 and rotatetherewith, they being first adjusted to bring their cut away portioninto engagement with the dogs 47 and 51 at the proper predeterminedtime. Thus as the worm 60 rotates the disks also rotate; the dogs, ofcourse havel been thrown out of engagement by means of lifting thehandle 44 to start the machine. As the handle 44 is lifted the operatingrocker arm 34-is tilted or rocked so as to throw the clutch A intoengagement which at the same time pulls the crank arm 90 which istightly fastened to the shaft 39 over therewith, which in turn pulls thebracket 98 therewith., thereby pulling the pins 85 and 94 out ofengagement with the pawl 78 and the lug and extension 96, therebyallowing the pawl 7 8 to operate the half round key in order to causethe fly wheel to drive the clutch mechanism. This it is readily seenimmediately starts the entire machine.

Now when the master drum has rotated far enough so as to have broughtal1 of the FID operating bars into operative engagement rwith .theproper mechanism, the :pawl 4?? will fall to its 'lowermost positionfrom 'the .cut edge lOl on :the fdial, n'herebyrocking the .39 :owingA.to the `tacit that :the enga ging lugs 91 von the crank `90 haveenough play vthererbetxveen `to allow @the operating rocker arm 34 toreturn Without eil'ectingthe anove- =ment fof the :crank farm f90.
